Rdmo

* better error handling when a project is without question catalog

* a new button to get default uri prefix
- the default uri prefix needs to be defined by an entry called `DEFAULT_URI_PREFIX` in the `local.py`
- add something looking like this `DEFAULT_URI_PREFIX = 'https://rdmo.uni-xyz.de/terms/'`

* user profile can now be deleted
- the profile deletion page is by default available
- nonetheless it can be explicitely switched on or off by an entry called `PROFILE_DELETE` in the `local.py`
- use `PROFILE_DELETE = False` to switch this feature off
- note that it is recommended to disable profile deletion when using Shibboleth or LDAP because RDMO can not delete users from these databases
